RENSSELAER – City police arrested a man on gun charges after he ran from a traffic stop Tuesday.

Sgt. Tony Nagengast said officers pulled over a car on Columbia Turnpike and passenger Ronnie Robinson, 19, of Troy jumped out and allegedly ran from officers.

During the foot chase, which also involved East Greenbush police, Robinson allegedly tossed a loaded .40 caliber handgun on the ground.

Robinson was charged with two counts of criminal possession of a weapon and resisting arrest and was sent to the Rensselaer County Jail with no bail.

The driver of the car, Stacey Moore, 43, of Castleton, was charged with second-degree criminal impersonation, DWI, third-degree aggravated unlicensed operation and seventh-degree possession of a controlled substance. She was sent to the jail on $2,500 bail, Nagengast said.
